Diamondback Mason Pro Bike 2014

As 29er bikes become more prevelant, bike companies continue to push
the envelope with new designs for the 29er market. Located in the
Pacific Northwest, Diamondback needed a 29inch offering that was a bit
more capable of handling local terrain that can often be aggressive if
not also wet and muddy. Enter the Mason Pro All Mountain hardtail. This
rig is slack and low slung—meant for today’s shredder who wants
efficiency on the pedal uphill but also the freedom to charge down the
other side with aggressiveness.

The Mason Pro features an All Mountain 6061-T6 Weapons Grade Aluminum
frame with a formed top tube, a formed and butted down tube, a tapered
head tube, a direct mount front derailleur mount, ISCG tabs and a
142×12mm Maxle drop out.

Loading up the front end is a Fox 34 TALAS 29 CTD air fork, 140mm /
110mm travel, open cartridge, with external rebound, butted alloy 1.5
tapered steerer, 34mm Easton aluminum stanchions, magnesium lowers,
w/QR15 thru axle. This also lends to a slack, 66.5 degree head angle.
Combine this with 433mm/ 17.05" long chain stays and you can clearly
see where this is going. This keeps the bike maneuverable, easy to
manipulate in downhill and aired out sections, and easier to get the
front end of the bike up with the slack head angle. Because the long
travel fork lifts the front end of the bike up pretty high, Diamondback
designed a formed, low top tube for better clearance over the bike.

Momentum – A larger
wheel enables one to carry momentum easier though obstacles.

Surface Contact –
29”wheels are less prone to sinking in soft material such as sand and
mud due to the larger contact patch causing lower ground pressure. The
longer contact patch increases cornering and straight line traction.

Stability – The relative
position of the bottom bracket/cranks to the axles in the wheels also
means that your relative center of gravity is lower. This results in a
feeling of riding “in” the bike rather than on top of it.

Tire Clearance – with
more tire choices than any platform, the 29”wheel easily accommodates
off road as well as commuting tires.

The drivetrain is stacked with a RACEFACE Respond w/ NEW 32t
Narrow-Wide single ring with outboard bearing bottom bracket . Combine
this with a SRAM X-9 Type 2 10spd rear derailleur and shifter, and a
SRAM PG-1030 10spd Cassette (11-36t) and you have a minimalist approach
with a variety of options to get you up the hill with ease. AVID
Elixir 5 Hydraulic Disc brakes with 200mm front & 180mm rear HS-1
rotors offer optimized stopping power when and where you see fit. Be
fully in control of the cockpit with the Raceface Respond stem and
handlebars, a 30.9mm Crank Brothers Kronolog Dropper post, and the DB
MASON Signature saddle.
